Abstract

The present invention provides an “update forwarder” function to facilitate downloading applications to mobile devices. The update forwarder receives updates on its “network side” from one or more device management servers, stores the updates, and then delivers them from its “device side” to one or more mobile devices. By using wired or short-haul wireless links on both its network and device sides, the update forwarder can reduce demand for the precious bandwidth of a widespread wireless network. The update forwarder can receive downloads during off-peak times for the device management servers and at times when the mobile device is turned off or otherwise unavailable. Downloads can be scheduled to be delivered only when the mobile device is not otherwise in use. The update forwarder can be implemented with little cost as one function running on a device, such as a home PC or local server, that already serves other functions.

Description

FIELD OF THE INVENTION

The present invention relates generally to wireless communications, and, more particularly, to distributing applications that run on wireless devices.

BACKGROUND OF THE INVENTION

Like most other computing devices, a mobile device requires that updates be downloaded to it for the applications running on it. (To make the present discussion easier, “applications” include all software and firmware components that run on the mobile device, including the operating system, any utilities, and databases, in addition to the software programs normally thought of as “applications.”) Also, completely new applications can be downloaded to the mobile device at its user's discretion.

On first consideration, nothing could be more straightforward than downloading updates or downloading new applications to a mobile device. The download process can use the same wireless communications capability that the mobile device uses when running its applications. Intricacies of wireless communications such as, for example, locating the mobile device, authenticating the device to the network, and negotiating to use wireless bandwidth, must have already been worked out before the mobile device could function at all. In order to download an application to the mobile device, therefore, “device management servers” (devices that store updates and new applications and then deliver them to mobile devices) can simply use the existing wireless infrastructure and techniques. Indeed, this is exactly how updates and new applications have traditionally been distributed to mobile devices.

However, the very simplicity of this traditional download method presents problems. When updating is so simple, updates become common, and the bandwidth needed to download them begins to compete with the bandwidth needed by mobile devices to actually run applications. This leads to longer download times and possibly to reduced performance for the running applications. In addition, downloads may not even be possible at certain times because the mobile device enters an area of spotty or non-existent wireless network coverage (or is turned off). When compensating for this, the device management servers are sometimes overloaded as they try to update multiple mobile devices during the limited time when those devices are reachable over the wireless network.

BRIEF SUMMARY OF THE INVENTION

In view of the foregoing, the present invention provides an “update forwarder” function to facilitate downloading applications to mobile devices. The update forwarder receives updates on its “network side” from one or more device management servers, stores the updates, and then delivers them from its “device side” to one or more mobile devices. By using wired or short-haul wireless links on both its network and device sides, the update forwarder can reduce demand for the precious bandwidth of a widespread wireless network.

In some embodiments, on its network side the update forwarder receives updates from device management servers via a wired or optical link such as a private line or the Internet. Because this communication need not occur in synchrony with delivering the downloads to the mobile device, the update forwarder can receive the downloads during off-peak times for the device management servers and at times when the mobile device is turned off or otherwise unavailable.

When downloading updates to the mobile device, the update forwarder's device side can use a wired link, such as a USB cable when the mobile device sits in its charging cradle, or a short-haul wireless link, such as Wi-Fi. These downloads can be scheduled to be delivered only when the mobile device is not otherwise in use.

The update forwarder can be implemented with little cost as one function running on a device, such as a home PC, local server, or wireless home gateway, that already serves other functions. Because of the low cost, many update forwarders can be set up which would substantially decrease the load on the device management servers. In the limit, a tree structure exists wherein the device management servers only update the update forwarders, and the update forwarders update the mobile devices.

DETAILED DESCRIPTION OF THE INVENTION

Turning to the drawings, wherein like reference numerals refer to like elements, the present invention is illustrated as being implemented in a suitable environment. The following description is based on embodiments of the invention and should not be taken as limiting the invention with regard to alternative embodiments that are not explicitly described herein.

FIG. 1 presents the devices in one embodiment of the present invention. A mobile device 100 communicates via wireless to a Radio Access Point 102. While shown in FIG. 1 as a cellular telephone, the mobile device 100 can be any wireless-equipped device such as, for example, a laptop computer or a personal digital assistant.

Through the Radio Access Point 102, the mobile device 100 can communicate with many other devices through an internetwork 104. The internetwork 104 can include other wireless links, wired links, the Public Switched Telephony Network, and the Internet. The other devices that the mobile device 100 communicates with include both mobile and non-mobile devices (not shown). The present invention is not limited by the nature of the devices with which the mobile device 100 communicates.

When software or firmware updates or new applications become available for the mobile device 100, a device management server 106 traditionally downloads the updates to the mobile device 100 via wireless through the Radio Access Point 102. As discussed above, this technique, though workable, is costly and often inconvenient.

The present invention provides an update forwarder 108. On its network side, the update forwarder 108 receives updates from one or more device management servers 106 and then delivers the updates through its device side to the mobile device 100. Instead of downloading over the rather costly wide-area wireless link (via the Radio Access Point 102), the update forwarder 108 can use a wired (e.g., cable, DSL, or internetwork 104) link to receive the updates from the device management servers 106. This download may be scheduled during off-peak times to reduce the load on the device management servers 106. At a convenient time, the update forwarder 108 delivers the updates to the mobile device 100 by using an inexpensive link, for example a short-haul wireless link (e.g., Wi-Fi) or a wired link to the charging cradle (not shown) of the mobile device 100.

No hardware need be dedicated to the update forwarder 108. The update forwarder 108 is a function that can run on a home PC, a departmental server, or a wireless home gateway that already serves some other function.

FIG. 2 presents a generalized overview of a procedure that can be used with an update forwarder 108. This overview is “generalized” because different embodiments implement different combinations of the steps of FIG. 2. This generalized discussion is followed by specific implementation examples discussed below with reference to FIGS. 3 through 6.

Particularly, the update forwarder 108 can include both control and download functions, but some implementations only support download, leaving all of the control to the device management servers 106. Control typically includes: initiating an update, authenticating the update forwarder 108 and the mobile device 100, discovering an appropriate update forwarder 108 to use, and delivering update status to the device management servers 106.

The network side of the update forwarder 108 communicates with the device management servers 106. In some implementations, the update forwarder 108 emulates a mobile device 100 to the device management servers 106, receiving updates and delivering status just as if it were a mobile device 100. In other implementations, the update forwarder 108 uses a special protocol when communicating with the device management servers 106. This protocol allows for a greater degree of control over the updating procedure.

As an example of the control made possible by a special protocol, step 200 of FIG. 2 shows an update forwarder 108 registering with one or more device management servers 106. For the sake of security and of update management, the device management servers 106 can be implemented so that they only deliver updates to registered update forwarders 108. Similarly, a mobile device 100 only receives updates from a registered update forwarder 108. During registration, a device management server 106 can tell the update forwarder 108 which mobile devices 100 it may update. This list is a subset of the list of all mobile devices 100 which the device management server 106 is assigned to update.

Before delivering an update to the update forwarder 108, the update forwarder 108 and the device management server 106 authenticate each other in step 202. Once authentication is complete, the device management server 106 delivers an update package to the update forwarder 108 in step 204. This package can include one update known to be needed by a particular mobile device 100. The package can also be a “bulk update” that includes multiple updates, some of which will go to one mobile device 100 and some to another. In this way, the device management server 106 can act as an update “wholesaler,” while the update forwarder 108 acts as an update “retailer,” paying attention to the particulars of delivery to individual mobile devices 100. This can greatly decrease the load on the device management server 106 because it only downloads a particular update once for each update forwarder 108 instead of once for each mobile device 100.

The update forwarder 108 is responsible for updating one or more mobile devices 100. In step 206, one of those mobile devices 100 is authenticated to the update forwarder 108. Then in step 208, the update forwarder 108 extracts current configuration and status information from the mobile device 100. This information can include:

an identifier of the mobile device 100;

a make and model of the mobile device 100;

firmware and software revision numbers for the mobile device 100;

a list of the applications already installed on the mobile device 100;

the amount of memory available on the mobile device 100; and

the type of the processor on the mobile device 100.

The update forwarder 108 uses this information to know which updates are appropriate for this particular mobile device 100. For example, the update forwarder 108 may have two or more versions of an update and will deliver the appropriate version based on the processor type and firmware revision number of each mobile device 100.

In step 210, the update forwarder 108 uses the information gathered above to deliver appropriate updates to the mobile device 100. In some embodiments, the mobile device 100 does not know that it is communicating with an update forwarder 108. Instead, the update forwarder 108 emulates a device management server 106 to the mobile device 100. Note that downloading updates to the mobile device 100 (step 210) need not occur in synchrony with downloading updates to the update forwarder 108 (step 204). Each of these steps is carried out when most convenient for the devices involved.

When the download is complete, the mobile device 100 in step 212 tells the update forwarder 108 of the results of the download, successful or otherwise. The mobile device 100 can also deliver updated information about itself (for example, the amount of memory available on the mobile device 100 may have changed as a result of the download). The update forwarder 108 delivers this information to the device management server 106. Steps 206 through 212 of FIG. 2 are repeated for each mobile device 100 to be updated by the update forwarder 108.

The following discussion illustrates three particular implementations of the general procedures of FIG. 2. Column 300 of FIG. 3 gives a useful name to each of these three implementations. Column 302 tells whether a given implementation of the update forwarder 108 supports only the download function or also supports the control function. Columns 304 and 306 tell how the update forwarder 108 communicates with a device management server 106 and with a mobile device 100, respectively. Note that other implementations beyond the three of FIG. 3 are possible and are contemplated. These examples are not meant to limit the scope of the invention as claimed.

FIG. 4 illustrates a first embodiment of the update forwarder 108. This is the “back-to-back agent” of row 308 of FIG. 3. Towards a device management server 106, the back-to-back update forwarder 108 emulates an update protocol running on the mobile device 100 and downloads updates for the set of mobile devices 100 that it supports. To its mobile devices 100, the back-to-back update forwarder 108 emulates an update protocol running on the device management server 106 and delivers updates to the mobile devices 100.

To perform its control functions, the back-to-back update forwarder 108 stores, for each mobile device 100 that it supports, a configuration record that includes:

an identifier of the mobile device 100;

a make and model of the mobile device 100;

firmware and software revision numbers for the mobile device 100;

a list of the applications already installed on the mobile device 100;

a network address of a device management server 106;

authentication credentials specific to the mobile device 100; and

authentication credentials specific to a device management server 106.

This information allows the update forwarder 108 to emulate the device management server 106 to the mobile device 100, including the authentication of step 206 of FIG. 2 and the discovery of status information of step 208.

The procedure of FIG. 4 can begin when the device management server 106 tells the mobile device 100 that updates are available for download. (This is optional.) When the mobile device 100 establishes connectivity with the back-to-back update forwarder 108, the establishment of connectivity triggers a discovery process between the mobile device 100 and the update forwarder 108. The update forwarder 108 learns the current status and configuration of the mobile device 100. In some embodiments, the update forwarder 108 responds differently to different types of connectivity. For example, the update forwarder 108 may choose to only initiate discovery when connectivity is established over a local link (such as a wired link to the charging cradle of the mobile device 100). The update forwarder 108 repeats the discovery process with the device management server 106.

When an update package becomes available, the device management server 106 notifies the back-to-back update forwarder 108 which then retrieves the package. If there is an update in the package that is appropriate for a mobile device 100, then the update forwarder 108 delivers that update to the mobile device 100. The update forwarder 108 receives the status of the download from the mobile device 100 and passes the status along to the device management server 106.

FIG. 5 shows a message flow for a “distribution agent” update forwarder 108 (row 310 of FIG. 3). As opposed to the back-to-back update forwarder 108 of FIG. 4, the distribution agent update forwarder 108 runs a distribution agent protocol with the device management server 106. By means of this protocol, the device management server 106 delegates some of its control functions to the update forwarder 108. In particular, the protocol allows:

the update forwarder 108 to register with the device management server 108;

bulk updates to be delivered to the update forwarder 108; and

the bulk updates to be synchronized.

In particular, the distribution agent update forwarder 108 can receives bulk packages containing many updates and then deliver only the appropriate updates to each of the mobile devices 100 that it manages. As before, upon completion of an update, the status of the update is sent to the device management server 106.

FIG. 6 shows message flows for a “download agent” update forwarder 108 (row 312 of FIG. 3). As with the distribution agent update forwarder 108, the download agent update forwarder 108 runs a special protocol with the device management server 106. This protocol allows the update forwarder 108 to register with the device management server 106, allows these devices to authenticate each other, and allows for bulk downloads to the update forwarder 108.

As shown in FIG. 6, the device management server 106 initiates the download process directly with the mobile device 100. Discovery takes place between the mobile device 100 and the device management server 106.

The device management server 106 can ask the mobile device 100 whether it prefers to work with any particular download agent update forwarder 108. If so, then the device management server 106 verifies whether the preferred update forwarder 105 is registered with it. The device management sever 106 directs the mobile device 100 to an update forwarder 108 to retrieve the update. The device management server 106 may override the mobile device 100's preference if, for example, the preferred update forwarder 108 is not registered with the device management server 106.

Through a synchronization process supported by the protocol between the chosen download agent update forwarder 108 and the device management server 106, the device management server 106 ensures that the update forwarder 108 has a copy of the needed update. The mobile device 100 then retrieves the update from the update forwarder 108. Upon completion, the mobile device 100 delivers its update status directly to the device management server 106.

Though it is not required, the present invention can be implemented using message exchanges defined by the Open Mobile Alliance Device Management (“OMA DM”) Protocol. Notification is provided by the OMA DM notification protocol; discovery by the OMA DM discovery protocol, and the OMA DM Firmware Update Management Object protocol can provide the actual downloads and the status updates. Using an OMA DM “get” operation, a device management server 106 can retrieve the values of specific named parameters (called “nodes”) from a mobile device 100.

In view of the many possible embodiments to which the principles of the present invention may be applied, it should be recognized that the embodiments described herein with respect to the drawing figures are meant to be illustrative only and should not be taken as limiting the scope of the invention. Those of skill in the art will recognize that some implementation details are determined by specific situations and by specific protocols used. Therefore, the invention as described herein contemplates all such embodiments as may come within the scope of the following claims and equivalents thereof.
